애플리케이션

General Western Blot Protocol:
  • Glycoprotein sample size: 500ng
  • Lectin Concentration: 0.1ug/ml

  1. Load samples at 500 ng of glycoprotein per lane
  2. Run 4-20% Bis-Tris SDS page gel
  3. Transfer gel to a PVDF membrane
  4. Block membrane for 1 hr at RT with RIPA buffer (R0278 Sigma)
  5. Incubate HRP lectin at 0.1ug/ml with RIPA buffer for 2 hours at RT
  6. Wash membrane 5 x 5 minutes with 25ml RIPA buffer
  7. Detect using chemiluminescent substrate (CPS1-120)

생화학적/생리학적 작용

PNA does not agglutinate normal human erythrocytes, but strongly agglutinates neuraminidase treated erythrocytes. PNA has potent anti-T activity similar to the anti-T antibody in human sera. The lectin can be used to distinguish between human lymphocyte subsets.

단위 정의

One unit will form 1 mg purpurogallin in 20 sec from pyrogallol at pH 6.0 at 20 °C.

물리적 형태

Contains sodium citrate

제조 메모

Prepared from peroxidase (P8375) using a modification of a published method, which favors low molecular weight conjugates. Repurified after conjugation by affinity chromatography.

Protein O-glycosylation has key roles in many biological processes, but the repertoire of O-glycans synthesized by cells is difficult to determine. Here we describe an approach termed Cellular O-Glycome Reporter/Amplification (CORA), a sensitive method used to amplify and profile mucin-type

Dicer is a crucial enzyme for the maturation of miRNAs. Mutations in the Dicer gene are highly associated with Pleuro Pulmonary Blastoma-Family Dysplasia Syndrome (PPB-FDS, OMIM 601200), recently proposed to be renamed Dicer syndrome. Aside from the pulmonary phenotype (blastoma)

Virus-like particle (VLP) technology is an alternative platform for developing vaccines to combat seasonal and pandemic influenza. Influenza VLPs are non-infectious nanoparticles that can elicit effective vaccine immunogenicity in hosts. B-cell-activating factor (BAFF, or BLyS) and a proliferation-inducing ligand (APRIL)

Ectothermal reptiles have internal pigmentation, which is not seen in endothermal birds and mammals. Here we show that the development of the dorsal neural tube-derived melanoblasts in turtle Trachemys scripta is regulated by similar mechanisms as in other amniotes, but

A non-replicating form of pseudotyped influenza virus, inactivated by suppression of the haemagglutinin signal sequence (S-FLU), can act as a broadly protective vaccine. S-FLU can infect for a single round only, and induces heterotypic protection predominantly through activation of cross-reactive
